A rocket sled ride at Holloman Air Force Base in New Mexico, United States. A rocket powered Aero Med Lab high speed sled carrying an ape primate in a protective suit and helmet moves on a track at high speed. It leaves behind heavy columns of black smoke. The sled equipped with a Mega-boom rocket engine is seen moving fast on the track and the helmet comes off of the ape test subject, before the sled decelerates with the aid of water brakes, and completes its run.
